disks,l enhancingl readl andl writel speeds.l However,l RAIDl 0l doesl notl providel faultl
tolerance.
Q:l Toml isl workingl asl al networkl administratorl forl al smalll financiall company.l Hel isl
lookingl forl al fault-tolerantl solutionl forl thel server.l Whichl networkl RAIDl levell providesl
al duplicatel copyl ofl onel hardl diskl drivel onl anotherl hardl diskl drive?
Answer:l B.l RAIDl 1
, Explanation:l RAIDl 1l mirrorsl datal betweenl twol disks,l providingl faultl tolerancel byl
ensuringl redundancy.l Itl isl suitablel forl applicationsl requiringl datal protectionl andl highl
availability.
Q:l Howl doesl SANl differl froml NAS?
Answer:l D.l SANl isl connectedl tol thel locall networkl system,l whilel NASl isl accessedl
remotelyl vial al WANl link.
Explanation:l SANl (Storagel Areal Network)l providesl block-levell accessl tol storagel devicesl
overl al dedicatedl high-speedl network,l typicallyl usedl forl enterprisel storage.l NASl
(Networkl Attachedl Storage)l providesl file-levell accessl overl al LAN/WANl network,l
